Tonight's TV picks: 'The Following' serves up a killer finale

"The Following" (9 p.m., Fox): We expect a killer season finale from this grisly series. Ryan and Joe (Kevin Bacon and James Purefoy) are forced to put their differences aside and work together in order to save the woman they both love.

"All About Ann: Governor Richards of the Lone Star State" (9 p.m., HBO): This profile of the late Texas chief executive recalls how she was born into poverty and rose to prominence after delivering the keynote address at the 1988 Democratic National Convention.

"Bates Motel" (10 p.m., A&E): Norman (Freddie Highmore) continues to shut out Norma (Vera Farmiga), who is desperate to connect with him. Maybe she should take up taxidermy.
